I'm still having pain from the surgery, and I woke just a little while ago. I couldn't go back to sleep, so I decided to work on Text File Splitter 2 UI some more. This is pretty close the final form. I'm still trying to figure out how to show tokens for the file pattern. I'm currently leaning towards popping up a dialog with a list of tokens and explanations.

Each splitting strategy will have its own custom configuration control. That's why the panel below the "Configure Strategy" header is empty. I'm going to use MEF, to allow people to create their own custom splitting strategies in C#. Hopefully, people will start sharing strategies with others, and create some cool stuff with it. This means that I will create a mini-SDK for this with sample code, when I get done.

Anyways, here's the latest screenshot:
